Revert "ACPI / EC: Enable event freeze mode..." to fix a regression
On Lenovo ThinkPad X1 Carbon - the 5th Generation, enabling an earlier EC event freezing timing causes acpitz-virtual-0 to report a stuck 48C temparature. And with EC firmware revisioned as 1.14, without reverting back to old EC event freezing timing, the fan still blows up after a system resume. This reverts the culprit change so that the regression can be fixed without upgrading the EC firmware.
